Given numbers are 398,263,385,400,775
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,263,385,400,775 is 49971367600.
Find LCM of 398,263,385,400,775 with Prime Factorization
| 2 | 398, 263, 385, 400, 775 |
| 5 | 199, 263, 385, 200, 775 |
| 5 | 199, 263, 77, 40, 155 |
| 199, 263, 77, 8, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 199 x 263 x 77 x 8 x 31 = 49971367600
Therefore, the lowest common multiple of 398,263,385,400,775 is 49971367600.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
398 x 263 x 385 x 400 x 775 = 12492841900000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
398 : 1, 2, 199, 398
263 : 1, 263
385 : 1, 5, 7, 11, 35, 55, 77, 385
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,263,385,400,775, is 1.
Now, the common factors can be found like this.
398:2x 199
263:263
385:5x 7x 11
400:2x 2x 2x 2x 5x 5
775:5x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 5 = 250
Therefore, the value for common factors is 250.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 12492841900000/(1x250)
LCM = 12492841900000/250
LCM = 49971367600
Thus, we can understand that the LCM of 398,263,385,400,775 is 49971367600.
